[mythtv-users] Perplexed on plextors (ConvertX)

Just a quick followup:
I never could get a set of kernel options under which the cold-plug
scripts would detect a "cold" plextor (either coldplug only detects an
already initalized plextor, or I still have configuration issues). If
the firmware has been loaded to it, then coldplug detects the unit on
subsequent computer reboots. Assuming that the plextor is detected,
MythTV functions with it, but it is much touchier about the device than
the plextor test app, gorecord. There seem to be many "almost right"
kernel configurations under which gorecord works fine, but MythTV does
not.
The option set that seems to mostly work for me (still have the
"completely cold" cold plug problem) is:
CONFIG_HOTPLUG=y
CONFIG_MODULES=y
CONFIG_KMOD=y
CONFIG_FW_LOADER=y
CONFIG_I2C=m
CONFIG_VIDEO_DEV=m
CONFIG_SOUND=y
CONFIG_SND=y
CONFIG_USB=m
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=m
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
Anyway, I'm up and mostly happy again. Oh, the kernel version I'm
using is 2.6.11 (gentoo-r11).
Now, I guess I just have to figure out the manual firmware loading
for when I cycle the power on the plextor (or figure out why coldplug
cannot detect the uninitialized device. (hotplug can)...
